2. Common Causes of Starting Problems in the CAT 246
Now that we’ve identified the critical components involved in starting, let’s look at some of the most common causes of starting issues in the CAT 246 skid steer.
2.1 Weak or Dead Battery
One of the first things to check when your skid steer won’t start is the battery. If the battery is weak or dead, the starter motor won’t receive the necessary power to turn the engine over.
- Causes: The battery may have drained due to prolonged inactivity, leaving lights or electrical components on, or it may simply be old and unable to hold a charge.
- Symptoms: The machine might make a clicking noise when you turn the ignition key, or it may not respond at all.
- Solution: Check the battery’s voltage using a multimeter. If the voltage is below 12.4 volts, the battery may need recharging or replacement. Clean any corrosion from the battery terminals, and ensure the battery is securely connected.
If the battery is in good condition but the engine still fails to turn over, the issue may lie with the starter motor or its solenoid.
- Causes: Over time, starter motors and solenoids can wear out due to frequent use or electrical issues. A faulty solenoid may fail to transmit power to the starter motor, while a worn starter motor may not engage properly.
- Symptoms: You might hear a clicking sound but no engine cranking, or the engine might turn over very slowly.
- Solution: To test the starter motor, try bypassing the solenoid by jumping the terminals directly on the starter motor. If the engine cranks, then the solenoid is likely the issue. If the motor doesn’t engage, the starter motor itself may need to be replaced.
A clogged fuel filter, a malfunctioning fuel pump, or air in the fuel lines can all prevent the engine from receiving adequate fuel.
- Causes: Over time, fuel filters can become clogged with debris or contaminants. Air bubbles in the fuel lines can cause the engine to lose its fuel prime, resulting in starting issues.
- Symptoms: The engine may turn over but fail to start, or it may start briefly and then stall.
- Solution: Check the fuel filter and replace it if necessary. If you suspect air in the fuel lines, bleed the system to remove any air pockets. Inspect the fuel pump for proper operation, ensuring it’s supplying fuel to the injectors.
If the ignition system is not functioning properly, the engine may fail to start, even if the starter motor is working and the fuel system is intact.
- Causes: The ignition switch, spark plugs, or ignition coil may be faulty. In older machines, ignition wiring may degrade, causing poor connections.
- Symptoms: The engine may crank but won’t start, or it may sputter and fail to run properly.
